HOMER A. TUNIS, 0F RINGWOOD, OKLAHOMA.

COUPLING.

Application led December 12, 1908.

To all whom 'it may concern:

Be it known that I, HoMnR A. TUNIS, a citizen of the United States,residing at Ringwood, in the county of Major and State of Oklahoma, haveinvented a new and useful Coupling, of which the following is aspecification.

The objects of the invention are, the provision in a merchantable form,of the device of the above mentioned class, which shall be inexpensiveto manufacture, facile in operation, and devoid of complicating` parts;the provision of novel means for locking and operating the retainingbolt;fother and further objects being made manifest hereinafter, as thedescription of the invention progresses.

The invention consists in the novel construction and arrangement ofparts hereinafter described, delineated in the accompanying drawings,and particularly pointed out in that portion of this instrument whereinpatentable novelty is claimed for certain distinctive and peculiarfeatures of the device, it being understood that within the scope ofwhat hereinafter thus is claimed divers changes in the form,proportions, sizes, and minor details of the structure may be made,without departing from the spirit or sacrificing any of the advantagesof the invention.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawing. A

In the accompanying drawing, Figure 1 shows my invention in perspective;Fig. 2 is a vertical longitudinal section thereof; Fig. 3 is atransverse section on the line A B.

To enable others skilled in the art to which my invention appertains, tomake and use the same, I will now describe my invention and explain itsoperation.

The invention comprises a housing 1, which may be of any form;preferably however, as shown, it comprises a base member 2 and sidewalls 3 outstanding from the face 4 of the housing. The lower end of thehousing 1 is provided with a central guideway 5, arranged to receive thepiston rod of a pump. A resilient tongue 6 is provided, the said tonguebeing rigidly attached at one of its ends to the housing 1 by means ofthe block 7. The lower end of the housing Specification of LettersPatent.

Serial No. 467,260.

1 is provided with yoppositely disposed, transversely alined openings 8and 9, in which is slidably mounted the retaining bolt 10, arranged tocross the guide-way 5 and to be terminably supported on opposite sidesof the guide-way 5, as shown. One end of the retaining bolt 10 isbifurcated to form standards 11, carrying a transversely disposed bolt12 about which is bent the free end of the resilient tongue 6 to forni apivotal connection between the tongue 6 and the retaining bolt 10.

A lever 13 is pivotally mounted in the housing 1 between the side walls3, and provided with a central opening 14 arranged to receive the tongue6. The lower end of the lever 13 carries a transversely disposedshoulder 15 arranged to engage the lower face of the tongue 6 in liftingrelation, as shown in dotted line in Fig. 2. This shoulder 15 is sopositioned upon the lever 13, relative to the pivotal connection 21 uponwhich` the lever is mounted, that, when the lever 13 is thrown downward,as shown in dotted line in Fig. 2, the retaining bolt 10 will bewithdrawn from the opening 9 and from the guide-way 5, butnot from theopening 8, the retaining bolt 10 thus being left in a position operativeto be shot forward into the opening 9 again, as hereinafter described.

A shoulder 16, integral with the housing 1, is transversely disposedbetween the side walls 3 to receive the thrust of the pitman of thewindmill. Between the outstanding side .walls 3, and abutting againstthe shoulder 16 is rigidly mounted the block 7 which if desired, may befashioned integral with the housing 1. vThe block 7 is provided with aseat 17 disposed parallel to the face 4 of the housing and arranged toreceive the iiXed terminal of the tongue 6. Lateral members 18 rise fromthe seat 17 and are disposed between the said seat 17 and the side walls3 of the housing 1. These lateral members 18 serve to retain the tongue6 from contact with the side walls 3 of the housing. The seat 17 lies ina plane outwardly removed from the plane of the face 4 of the housing,and, as shown in Fig. 2, the tongue 6 rests normally at some distancefrom the face 4. By this construction it is possible to bend manuallythe tongue 6 toward the face 4, to increase the resiliency of the saidtongue, to adjust the speed with which the retaining bolt 10 moves, andto secure a quicker lock; should these adjustments become necessary.

Referring now to Fig. 3, it will be seen that the inner faces 19 of thewalls 3 are made to Hare laterally, and that, as shown in Figs. 1 and 3,the lever 13 is provided with laterally flaring, resilient 4wings 20,positioned to engage the faces 19 when the lever 13 is in the positionshown in solid line in Fig'. 2, whereby the said lever 13 may be lockedbetween the faces 19. The movable end of the lever 13, being inclosedbetween the wings 20, is confined against lateral movement, and thepossibility of the retaining bolt 10 becoming jammed in the opening 8,kwhen the said bolt 10 is moved from the position shown in Fig. 1, isthus reduced.

The operation of the device is as follows:

My coupling is attached to the pitman of a windmill, as shown in dottedline in Fig. 2, the said pitman abutting against the shoulder 1G asshown. The piston rod of the pump is arranged to reciprocate in theguide-way 5, the parts of my invention being in the positions shown inFig. 1, and in dotted line in Fig. 2.

Then it is desired to eii'ect a coupling the lever 13 is moved to aposition intermediate the dottedand solid line positions of Fig. 2,whereby the retaining' bolt 10 willV be made to bear against the pistonrod (not shown) of the pump, and there be held by the resilient tongue6. As my coupling reciprocates with the pitinan of the windmill, the endof the retaining bolt 10 will traverse longitudinally, the upperterminal of the piston rod of the pump, until it, the said bolt 10,encounters one of the transversely disposed openings commonly providedin the upper terminal of the piston rods of pumps designed for use withwindmills. Impelled by the tongue 6, the bolt 10 will enter one of theseopenings in the piston rod of the pump, and move into the position shownin solid line in Fig. 2, and designated by the numeral 10.

From the intermediate position hereinbefore mentioned, the lever 13 ismoved to the position shown in solid line in Fig. 2, in which positionit will be retained by the peculiar relation between the wings 2O andthe faces 19 as hereinbefore described, and particularly delineated inFig. 3.

When it is desired to disconnect the pump @4eme from the windmill bywhich it is operated, the lever 13 is moved from the position shown insolid line in Fig. 2 to the one shown in dotted line therein. Duringthis operation, the shoulder 15 will have engaged the under face of thetongue 6, raising said tongue, and withdrawing the bolt 10 from theopening 9 and from the guide-way 5, the terminal of 'the bolt 10 restingin the opening S, as shown in dotted line in Fig. 2, whereupon theconnection between the pitman of the windmill and the piston rod of thepump will be broken.

Having thus described my invention, what l claim as new and desire toprotect by Letters-Patent, is:

l. ln a device of the class described, a housing having outstanding sidewalls provided with beveled inner faces; a tongue disposed between thewalls; a locking bolt carried by the tongue; a lever pivoted between thewalls and being arranged to lift the tongue, the lever being providedwith resilient flaring wings to engage the beveled faces of the walls.

2. ln device of the class described, a housing having outstanding sidewalls provided with beveled inner faces; a tongue disposed between thewalls; a locking bolt carried by the tongue; a lever pivoted between thewalls and arranged to lift the tongue, the lever being provided withresilient wings to engage the beveled faces of the walls.

3. 1n a device of the class described, a housing having outstanding sidewalls; a tongue disposed between the walls; a locking bolt carried bythe tongue; a lever pivoted between the walls and arranged to lift thetongue, the lever being provided with resilient Haring wings to engagethe walls.

4l. n a device of the class described a housing having outstanding sidewalls; a tongue disposed between the walls; a locking bolt carried bythe tongue; a lever pivoted between the walls and arranged to lift thetongue, the leverI being arranged to be wedged between the walls.

ln testimony that I claim the foregoing as my own, I have hereto aliixedmy signature in the presence of two witnesses.
